Question

HELP NEED DETAILED ANSWER 20 POINTS

Answer 1

40%.

Explanation:

Let's suppose the original price of the radio was $100.

Then its price after a 20% reduction is $80.

A 25% reduction on the $80 gives us 80 - 0.25 * 80 = 80 - 20 = $60.

So the overall percentage reduction = 100 - 60 = 40% (answer).

Answer 2

60%

Explanation:

That 20% off on the first day of the sale corresponds to multiplying all original prices by (1.00 - 0.20), or 0.80.

Similarly, the further 25% discount corresponds to multiplying this 0.80 by 0.75: (0.80)(0.75) = 0.60.

The overall discount, on the last day of the sale, will be 60%.
